Network chargers

Smartphones have become an integral part of people's lives in the modern world. They help in entertainment, study, work, they have a lot of advantages, but there is also one important and not very convenient nuance - they are regularly discharged.

To prevent a “smart” phone from letting its owner down at the wrong moment, it is better to always have a mains charger at hand. With its help, you can recharge your smartphone (and not only) at any time, if there is an electrical network nearby.

What is a USB phone charger?

A USB phone charger is a compact device that is connected on one side through a power outlet to the network, and on the other through a USB cable to the device that needs recharging. An electric charge flows through it.
You can also charge your smartphone from a computer or laptop - via a USB cable, connecting it to the appropriate connector. USB charging allows you to quickly and safely charge your gadget to always stay connected.

Types of USB chargers

If you are going to recharge the device through an outlet, you need a charging adapter to which you connect a USB cable. It may have one cord outlet or several, so that more devices can be connected at the same time.

USB chargers come in different types depending on the connector standard:

• Type-A is a rectangular connector that is most common. Devices are connected and charged through it;
• Type-B - can be either rectangular or square. With its help, devices are connected to each other;
• Micro USB is a type of rectangular connector characterized by its small size. Provides high speed of the “procedure”;
• USB-C is the newest standard, gaining popularity due to its versatility and convenience. It can be used both for charging and for transmitting information.

Another type of USB charging is an external power supply for a smartphone or a power bank. It has a charging unit (battery) that can be charged for future use from the mains or from sunlight in order to use this resource for the phone later, when there is no outlet nearby.

Parameters of USB chargers

To buy a suitable unit for charging your phone, you need to know the main characteristics that you should focus on when choosing it. These include:

1. Output current. The power supply for the phone supplies current to the device with a certain strength, which determines the charging speed. The output current level indicates the charging power. This is a parameter in amperes (A) - the higher it is, the faster the gadget will charge. It is important to consider what output current the device needs so that these indicators coincide or the difference is insignificant;
2. Output voltage. This indicator indicates what voltage will be supplied to the device through the adapter to charge the phone. The standard level is considered to be 5V, but there are devices with voltages of 9V and 12V. The higher it is, the faster the phone charges. In order not to damage the devices being charged, you need to know what voltage they require and choose suitable charging units;
3. Length of cable. It is important to choose a cord with the correct connector and the correct length. Optimally - from 1 to 2 meters, since this allows you to conveniently connect the phone to the charger and at the same time protects against energy losses that slow down the speed of the charging process.

If you need to charge your smartphone on the go, it is better to buy a charging unit with a short cable so that it does not get tangled or interfere.

Technological innovations in phone power supplies

Under normal conditions, the phone adapter and cable need to be connected for several hours so that the device can be fully charged, but there are technologies that can significantly speed up the process. Among them:

• Quick Charge - fast charging. Technology that allows you to charge your phone battery by 40-60% in 30 minutes. It has a function for automatically determining the voltage required for charging. For fast charging, both the device and the charger must have appropriate support;
• Power Delivery is a charging standard via a USB-C port that involves transmitting energy with increased power. The advantage is that it can be used for devices that require different power during the charging process, since the devices can coordinate its parameters, as well as current and voltage, among themselves. In addition, this standard allows you to perform two actions simultaneously - transfer data and charge the device.

Innovative technologies make charging devices from manufacturers more convenient and efficient to use.

USB charger safety

The safety of its use depends on the quality of the materials from which the charger connected to the network is made.

Devices whose body is made of metal (aluminum) or reinforced, fire-resistant and impact-resistant plastic will be more reliable and safe.

Tips for caring and using the AC charger

Network chargers must be disconnected from the network when the gadget is fully charged so that the battery does not gain excess energy (this reduces its service life).

In order for the device to work longer, it must be protected from contact with water, temperature changes, falls from a height, and strong shocks.

It is better to fold the cord neatly, rather than tying it in a knot or tangling it, and when turning off charging, you should not pull it (this may lead to breakage of the cord).

At the time of charging, it is recommended to place the gadget on a flat surface, and not leave it hanging on the wire (this can cause the cord to tear).
